During the last week Chandra completed the observing schedule as
planned.

Chandra passed through the eighth and ninth eclipses of the fall
season on Oct 9 and 12 respectively, with nominal power and
thermal performance. A real-time procedure was executed on Oct
11 to back out a patch to the Control Processing Electronics
(CPE). The patch had configured the CPE for the Draconid meteor
shower on Oct 8. A second real-time procedure was executed on
Oct 13 to update the on-board ephemeris. A third real-time
procedure was executed on Oct 13 to re-initialize the flight
software Thruster Command Processing subfunction in order to
prevent the occurrence of an overflow condition.

A Chandra image release was issued on Oct 12 describing
observations of G299.2-2.9, a supernova remnant found about
16,000 light years from Earth in the Milky Way galaxy. Evidence
points to G299.2-2.9 being the remains of a Type Ia supernova.
Because it is older than most supernova remnants caused by these
explosions, at an age of about 4500 years, G299.2-2.9 provides
astronomers with an excellent opportunity to study how these
objects evolve over time. For details see:
